Luckily I have a few real optics that I can use haha, although my dad probably won't allow me to use my trijicon for my spr hahaha! Although I’m sure he won’t mind me using my old Leupold.
I would trust ANY quality optics to withstand the piddly rigors of airsoft simulated combat.
After all, what kind of self-respecting brand would not warranty their product knowing that it was broken by a teenager with a BB gun?
"Dear Trijicon, I thought your products were tough, until I broke an ACOG playing AIRSOFT!"
"Dear Johnnie, there is a package en route to your residence. Do not be alarmed by the size of the box, or the quantity of optics therein. Pass them out to your friends, and see if they can break them, too."
So, if you can break it on a BB gun, it doesn't belong on your firearm.
